FORK-GRID FOR LOOMS.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed January 28, 1968. Serial No. 413,124.

a citizen of the United States, and resident of Hopedale, county ofWorcester, State of Massachusetts, have invented an Improvement inFork-Grids for Looms, of which the following description, in connectionwith the accompanylng drawing, is a specification, hketletters on thedrawing representing like par s.

This invention has for its object the production at small cost of asimple, efiicient and durable fork-grid for looms so constructed andarranged that its manufacture is greatly simplified and cheapened whileat the same time being particularly ad'a ted for use with very li ht orfine yarns ant with forks delicate in their action.

Fork-grids are commonly made of castmetal, and the bars forming the gridor grating roper have to be carefully machined and finis ed order topresent a smooth surface whlch will not catch the yarn.

When using very fine and light yarn as filling the fork must be delicateand quickly responsive in its action, and it is highly desirable thatthe grid bars be small as well as smooth and rounded, a result verydifficult to secure in even a limited way.

My present invention overcomes the obj ections attendant upon the usualcast-metal grids and secures at the same time the desired results aboveset forth.

Figure 1 is a perspective view of a forkgrid embodying one form of myinvention; Fig. 2 is a right-hand side elevation thereof.

In accordance with my invention I make the body portion of cast-metal,such as brass, or other desirable metal easily cast, and the bars aremade of wire of the desired diameter, the ends of the bars being firmlyand permanently embedded in the cast metal.

Referring to Fig. 1 the bodyportion 1 is substantially -shaped in sideelevation, with laterally extended head and foot portions 2, 3, parallelto each other and at right angles to the body, the latter at itsopposite side hav ing a lateral extension or lug 4, provided with a slot5 to receive the usual bolt by which the grid is secured in place'on thelay.

The part of the grid so far described is cast in a suitable mold, andinto the head and foot portions are permanently embedded the ends of-thebars. Said bars are made of wire, preferably cylindrical, and hereinthey are shown as substantially E-shaped, said bars being located inparallel vertical planes.

The main arts 6 of the bars are vertical and sustain flie filling, theupper and lower ends being bent rearwardly, at 7 and 8, and are embeddedat their extremities in the metal forming the head and foot portions 2'and 3, respectively, see dotted lines Fig. 2.

By this construction machining is obviated, with its cost, the bars areerfectly smooth and can be as fine or smafi in diameter as necessary,and they are rigidly and firmly held in place by the heavy cast-metalpart of the grid.

The bend given to the bars brings their vertical portions into properposition to sustain the filling while their rearwardly extended upperand lower ends act as braces to maintain the bars rigid, as well asaffording ample space for the fork-tines to enter when the filling isabsent.

The particular shape of the cast-metal portion of the grid may bealtered and the bending of the bars varied to correspond, withoutdeparting from the spirit and scope of my invention.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. As a new article of manufacture, aforkgrid for looms comprising a cast-metal body having laterallyextended head and foot portions, and an attaching lug, and wire barsarranged in parallelism and bent at their upper and lower ends, theextremities of such ends being permanently embedded in the metal formingthe head and foot portions of the body.

2. As a new article of manufacture, a forkgrid for looms comprising acast-metal body having laterally extended head and foot portions, and aseries of E-shaped wire bars arranged in parallelism and having theextremities of their upper and lower ends permanently embedded in themetal forming the head and foot portions of the body:

3. As a new article of manufacture, a forkgrid for looms comprising anE-shaped castmetal body having parallel and laterally extended head andfoot portions, and a series of round wire bars arranged in parallelismand also E-shaped, the upper and lower ends of their upper and lowerends permanently the bars being permanently embedded in the united withthe head an d. loot portions 01' the metal forming the head and footportions of body. the body.
